TRUE M. AVERY, OF GLENS FALLS, NEW YORK, ASSIGNOR TO THE UNION BAG & PAPER COMPANY, A CORPORATION OF NEW JERSEY.

MECHANISM FOR CONTROLLING THE RUNNING or A WEB or PRINTED MATERIAL.

To all whom it may concern:

Be it known that I, TRUE M. AVERY, a citizen .of the United States, residing at Glens Falls, New York, have invented certain new and useful Improvements in Mechanism for Controlling the Running of a Web of Printed Material, of which the following is a clear, full, and exact description.

This invention relates to mechanism for controlling the running of a web of printed material such as wall paper, paper for paper bag, etc. It is customary to print advertisements which are to appear on paper bags on a web of paper before the bags are made up in a paper bag machine, and it is desirable to cbtain a register or control of the web in its pas age through such paper bag machine, which operates on it at points or intervals which have first been designated or fixed when it isrunthrough the first machine. It is also desirable in cutting out wall paper borders and designs to run a web of paper on which the border or design is printed through a machine or mechanism in which a registry of the cutters with the borders or designs can be obtained. It is also desirable to obtain such a registry in a second printing press while the latter is to impose an imprint upon a web which has already been printed in another machine. The present invention has the above and other objects in view such as the electric control, through the medium of a specially prepared web, of the means whereby such registrations are obtained.

These being among the objects of the present invention, the same consists of certain features of construction and combinae tions of parts to be hereinafter described and then claimed with reference to the accompanying drawings illustrating desirable em odiments of the invention, in which Figure 1 is a side elevation of one embodiment of the invention in which it is shown as applied to mechanism provided with draw-rolls which are timed from the web of printed material so as to obtain the desired registry;

differential gearing shown in Figs. 1 and 2; Fig. 6 is a section on the line 66 Fig. 5;

Fig. 7 is a side elevation of a modification of the clutch mechanism and differential gearing; Fig. 8 is a plan of another form of gearig. 9 is a side view of the parts shown in Figs. 8 and 10; and

Fig. 10 is a section on the line 10-10, Fig. 9.

In carrying out the present invention, the web of paper or other material is preferably perforated along its margin simultaneously with the printing of the paper in the printing press. The web 11 is clearly shown in Fig. 2 as provided with linear perforations 12 extending along one of its margins, the perforations being equidistantly spaced apart, so that the said perforations can establish an accurate control of the second machine or mechanism through which the over an electrical control device or other suitable control device which is located in a plane somewhat above that of said idlcrs.

The electrical control device mentioned is shown in F gs. 1 and 2, and a part thereof is shown in Fig. 3. Briefly, this device com- 7 prises a guide-roll 17 for the web, upon which roll there is located at one end a loose collar or metallic ring 18, which is provided with a series of pins or teeth 19 which are equidistantly spaced around said ring for a distance corresponding with the distance between two adjacent perforations on the perforated web. The said ring is adapted to slip or turn slightly in one or the other direction with respect to the roll 17. During this relative movement, a lug 20 on said ring is adapted to strike one or the other of two insulated electrical contacts 21, 22. A battery 23 supplies current. and one side of the battery may be grounded upon the frame 14, while the other side of said battery is connected by means of wires 24, 25, with electromagnets 26, 27 from which wires 28, 29,

V respectively lead to brushes 30, 31, which are rated web deviates from the peripheral speed of the roller 17, which is timed to the speed of the machine or mechanism WlllCh operates on the web the loose ring 18 will shift relatively to said roller. If the speed of the web is greater than roller 17, the lug 20 will be brought against contact 21, thus .completing a circuit which will energize the magnet corresponding with said contact 21. If the speed of the web becomes less than roller 17, the lug 20 will make electrical. contact with the contact 22 and thus complete a circuit which will energize the other magnet. As the web does not hug the roll 17 very tightly,

it will slip one way or the other without 1 much friction.

The function of the electromagnets 26, 27, will now be described. .Magnet 26 may conveniently be termed the slow-down mag net, and magnet 27 the speed-up magnet,

and said magnets are adapted to control suitable clutch mechanism. Referring to Figs. 1, 2 and 4, one form of clutch mechanism comprises a shaft 33 which is constantly driven from a suitable source of power and is provided with a bevel gear 34 which meshes with a bevel gear 35 upon a shaft 36. This shaft is preferably arranged in vertical position and is mounted upon the frame 14. Upon this shaft there are located friction cones 37, 38, which have a key and groove connection therewith so that ,they will not only be continuously turned iwle direction by saidshaft but are slidable upon sa d shaft. Friction cone 38 is adapted to cotiperate with friction cone 40 which is mounted loosely upon the shaft 36 in a fixed location, and the. cone 40 is provided with .a

hub on which is located-a bevel gear 41, which meshes with .a bevel gear 42 located upon a shaft 43 which is suitably mounted on the frame 14. Friction cone 37 is adapted to cooperate with a friction cone 44 also mounted upon shaft 36 and carrying a bevelgear 45 which is also in mesh with bevelgear 42 at a point diametrically'opposite bevel-gear 41. From this construction and arrangement it will be clear that when the friction cones 38, 40, are in engagement, the shaft 43 will be turned in one direction and that when the cones 37 and 44 are in engagement, said shaft 43 will be turned in opposite direction. *The coiiperating pairs of cones are caused to engage at different times by the energization of'the magnets 26 and 27, one of which is energized when its corresponding insulated contact is engaged by the lug 20 on the roll 17. To this end the armatures of said magnets are pivotally connected with levers 46,47, respectively, which are pivoted to the frame 14 and 46 and 47 and are provided with forks which engage with grooved hubs of the friction cones 37, 38. When one or the other of the -levers 46, 47, is operated by its magnet, it causes the engagement of the concomitant cones, and this engagement lasts only as long as it takes to shift the perforated web of paper to proper position, such shifting automatically breaking the circuit through the lug 20 so that the magnet is dee'nergized, at which time a spring 50 connecting the actuating levers 46, 47, retracts the shiftable cone of the pair of cones which were in engagement at the time. When this action is taking? place, one of the pinions 41, 45, rotates the bevel-gear 42 in a direction corresponding therewith, which direction of rotation has been selected by the appropriate magnet.

Shaft '43 before mentioned, is provided with a worm 5] which turns with the shaft in one or the other direction according" to which of the magnets has been energized.

Referring more particularly to Fig. 5, it

will be seen that the worm 51 is in mesh with a worm-wheel 52 which is mounted ing-s0, it should be stated that the shaft 53- is constantly driven and carries a draw-roll 54, which 'coiiperateswith a draw-roll 55 intended to draw the web of printed-or similar material at the proper rate of speed. Said draw-rolls may be assumed to be the draw-rolls of a paper bag-machine, with which is usually associated means for forming the paper into tube. means is, however, omitted herein. Under the present invention it is desired to cause the proper registry of the imprint on the web of paper with a cutting device 93,.- which may be a pair of cutter rolls as shown, or substitute cutting means. such as is well known in paper bag machines. Said cutting Such forming device is timed to operate at the same speed I as roll 17, for which purpose it may be operated through an intermediate train of gears, comprising gears 94,- 95, asshown in Fig. 2. Ifthe cutting device 93 is substituted by a printing roll, a proper registration of the imprint caused by said printing roll will be obtained withthe matter already printed on said web. On the other stituted-by a cutter roll such as used in wall pap'ercutting machines, which cutter under "64 of shaft 53, thereby rotatin the present invention is timed to a predetermined speed of the web of material so that borders and designs will be brought substantially in register with the cutters. Frequently the shaft 53 which is timed under the present invention, will cause the roll thereon to travel at a peripheral speed which is different fiom the predetermined speed for the web of material. Sometimes the web will slow down and at other times will speed up, but in order to obtain the proper registration, means such as under the present invention are provided, said means preferably comprising the differential gearing above referred to.

In addition to the worm-wheel 52 before mentioned, the differential gearing comprises a gear 56 mounted loosely upon the shaft 53 and having external spur teeth 7 and internal spur teeth 58. One of the pinions of a pair of constantly driven pinions 59 meshes with the external teeth 57 as shown in Figs. 1 and 2, said pinions being connected by the intermediate gears 94 before mentioned, with a gear-wheel 60 located on one end of the roll 17. On one side of the worm-wheel 52 thereis fastened on a stud 62 an intermediate pinion 63- which is in mesh with the internal spur teeth 58 of gear 56, and diametrically opposite said point of engagement said intermediate pinion 63 is in mesh with a gear 64 keyed t'o shaft 53. It is clear that the constantly driven loose gear 56 imparts its motion through its internal teeth 58 and the intermediate pinion 63 to the keyed-on gear the drawroll on said. shaft. Worm-whee 52 is ordinarily locked against rotation while said gears drive the shaft 53 constantly. But when the web of printed material begins to creep or get out of register, with the cuttinoor printing rolls, it is retarded or accelerate by the turning of the worm 51 and wormwheel 52 produced by the action of the previously described detecting and controlling means comprising the electromagnets. When the worm-wheel 52 is turned, the intermediate pinion 63 is moved through a circular path in one or the other direction as is obvious. 4

A modification of the clutch mechanism is shown in Fig. 7, in which electromagnets 26" and 27 corresponding with magnets 26, 27, are employed. A miter gear 65 mounted in a suitable frame 66 meshes with a miter gear 67 whichis located on a shaft 68, which is driven continuously by the miter gear 65. At right angles to the shaft 68 there is a shaft 69 which is adapted to be rotated at intervals, whenever the web of paper is out of registry, to which end shaft 68 carries a bevel-gear 70 which is in mesh with pinions 71, 72 on said shaft 69. Pinions 71, 72, are loose upon shaft 69 and respectively carry friction cones 73, 7 4, which are respectively associated with coiiperating cones 75, 76, having a tongue and groove connection with shaft 69, and therefore adapted to rotate shaft 69 whenever coacting cones 74, 76, or 73, 75, are brought into engagement. Such engagement is efl'ectuated by the magnets 26, 27, acting through levers 77, 78. At the center of the shaft 69 is a worm 79, which engages worm-wheel 80, mounted on draw-roll shaft 81. The differential ear controlled by said Wormwheel is indlcated in dotted lines only, and

the details of its construction may be the same as that previously described. This modification of the invention differs from ,the one previously described in that theconnection is more direct and the friction cones 75, 76, which, are directly actuated by the electromagnets, except when in frictional engagement with cones 73, 74, respectively, and which drive the shaft 69, remain stationary. Furthermore, the friction cones 73, 74, revolve continuously in contra-distinction to the reverse in the modification before described.

A modification of the differential gear is shown in Figs. 8, 9 and 10. In this modification a gear 83 turns loosely upon a drawroll shaft 84 and one face thereof is provided with a bevel-gear 85 with which meshes a bevel pinion 86 which also meshes with a bevel-gear 87' keyed to said shaft 84. Ordinarily the driven gear 83 drives the shaft 84 at a continuous rate of speed, at

which time the pinion 86 is locked in one.

position with respect to the shaft 84. In

order, however, to time the speed of the web with respect to the predetermined speed of the cutters 93 or printing device, said pinion 86 is so mounted that its axis can be shifted around the shaft 84. To this end the pinionshaft 88 is mounted in a radial direction in the Worm-wheel 89, said pinion turning within an opening 90 at one side of said worm-wheel. When the worm 91 turns the worm-wheel 89, the axis 88 of pinion 86 is displaced with reference to shaft 84 in one or the other direction, depending upon which of the electromagnets has been energized, thereby obtaining adifierencein the rate of speed of the shaft 84 and hence the draw-roll. Any suitable clutch mechanism can be employed in connection with this modification of the differential gear.
